With Navien's Ready-Link® cascading technology, when a unit gets up to 80% capacity the next unit will turn on to help meet requirements. The flow on demand ratio will continue until all 32 units are generating hot water as needed. The Navien cascading system also balances out the workload of each unit for longer life.
Building penetrations are reduced with Navien's common venting feature.
Navien’s new backlit EZNav™ control panel uses simple text and icons to make set up, operation status and troubleshooting faster and easier than ever before.
Designed for recirculation of domestic hot water in applications where a dedicated return line is not available. External pump neccessary not included.
Part No. PFFW-001, NaviCirc Kit: 30022965A. External recirc pump and check valves not included.
NaviLink & NaviLink Lite make it easy to communicate with your Navien systems anywhere internet service is accessible. The NaviLink system attaches easily to any new or existing* Navien tankless water heater, combi‐boiler or boiler. NaviLink Lite is great for single residential units and magnetically mounts to the side of the unit or can easily be mounted on the wall. Also, NaviLink Lite does not require external power.
